delay-load

I have some NUnit tests which uses a TestCaseSource function. Unfortunately, the TestCaseSource function that I need takes a long time to initialize, because it scans a folder tree recursively to find all of the test images that would be passed into the test function. (Alternatively it could load from a file list XML every time it's run, but automatic discovery of new image files is still a requirement.) Is it possible to specify an NUnit attribute together with TestCaseSource such that NUnit does not enumerate the test cases (does not call the TestCaseSource function) until either the user

I've got a C# project (call it MainProj ) which references several other DLL projects. By adding these projects to MainProj 's references, it will build them and copy their resulting DLL's to MainProj's working directory. What I'd like to do is have these referenced DLL's be located in a subdirectory of MainProj 's working directory, i.e. MainProj/bin/DLLs, rather than the working directory itself. I'm not a very experienced C# programmer, but coming from the C++ world, I'm assuming one approach would be to remove the project references and explicitly load the required DLL's by path and
